Sorry for ignoring this for so long. This is going to be a fairly complex
module to maintain and it is VERY tightly coupled with Stellar. This means
that if we want to officially add this feature it will place an additional and
substantial burden on people making changes to Stellar.
I am happy to lead this but it should be something that is overwhelmingly
supported by the community. It will take a lot of effort from multiple people
to make this comprehensive and robust. I would need volunteers to help me.
Might make sense to revive this once we are confident Stellar is very
stable and won't change much. Not sure if that will ever happen since it's so
flexible and has already evolved so much :)
